Research demonstrates that the danger of sand production decreases through controlling the time of pressure release. The critical drawdown pressure increases because of the formation of compaction zone in the fracture creation in screen out fracturing.
研究表明,控制开井降压时间可有效降低出砂危险,另外,脱砂压裂造缝压实区的形成可在一定程度上提高临界生产压差。

But Afghan member of parliament Fawzia Koofi says she hopes the drawdown will continue based on success on the ground, not on internal pressure in NATO countries.
但是，阿富汗议会议员考兹亚·库费说，她希望北约驻军的缩减，是基于地面形势的成功，而不是北约国家内部的压力。
We can find that there is apparent peak value on the flow curve, the driving pressure differential corresponding to the peak value is the feasible drawdown.
发现流量曲线存在明显的峰值，该峰值对应的驱动压差就是合理生产压差。
When the pumping flow increases, the absolute values of pumping and injection drawdown were increased linearly on the whole, so the pressure of pumping and injection was increased.
抽水流量增加，抽、回水口降深绝对值基本呈线性增加，从而增加抽水和回灌压力。
